Y' Be vit known thatl, FREDERICKQW. -LIN- AKER, a subject of the KingoffEngland, residing 'at Dubois,vin the county of Clear- -ield and -State -of Pennsylvania, have invented certain new and useful Improvements in Protective Sheathin'g for Soot-Cleaner Distributing-Pipes, of which the yfollowing is a specification.

Figure 1 is a view in elevation showing manner of installation of the sheathing; on thedistributing pipe of ay soot cleaner applied'to afhorizontal Yor vertical type tube boiler, i

Fig. 2 is a longitudinal sectional view of one lform of the protective sheathing, the sections being broken away, and a portion of the distributing pipe being shown -in dotted lines, s

Fig. 3 is a similar view of another form of the sheathing, -showing thesheathing formed of alternate male sections and female sections, Y 'f Fig. 4 is a similar view showing the sheathing formed'V of lcombined. male Aand the line V--V of F ig.`3, and

Fig. .6 is a perspective View partly'broken away of one ofthe section connector elements of the form shown in Figs. 1 and 2.

In boiler flue cleaners of that type in which the soot is removed from the tubes and other surfaces of the boiler by jets of steam blown from a perforated pipe generally known in the art as a distributing pipe, difficulty has been encountered in protecting the distributing pipe from the in-` tense heat to which same is subjected.

It has been proposed, and attempts have been made to provide these distributing pipes with a cast metal sheathing, to prevent the pipe from being burned out, but these attempts heretofore have not been entirely successful, due to the cast iron sheathing having a different coefficient of expansion y, Specification of Letters Patent.` 1 1360.2, applicati@ mea March aaieisfseriarivo. 225;s47.'-

Y buckling and bending of the entire blower element, 'andiiwhen dilerent sections were "Joined together, the strain yput upon' the joints, due to the growth of thecastvir'on, was so 'excessive that the join ts-v vouldv break designed al cast iron sheathingfmade fup in apart, and the blower element Vor elements i' "become useless.

grows, one piece simply telescopes stood however that 'changes maybe made as 4 may be required for adapting the sheathing` to the blower elements with which., diflferent types of boilers are equipped, without departing Ifrom vthe spirit of .the invention or scope of the same as claimed. Y

In Fig. 1 the distributing pipe or blower element 10 is inserted through the wall 11 of the furnace in the usual manner, it being understood thatthe sleeve 12 in the boiler wall through which the blower element is introduced, is considerably larger than the element itself, as the bric ork in expanding, is otherwise liable to cause the element to bind. Of course, provision is made for preventing air leaking into the boiler through'this opening, which maybe done in any desired or approved manner,- different forms of which are known in the trade, and therefore not herein shown.

The sheathing as shown in F ig. 2 'of the drawings, consists of a pluralityv of relatively short sections which are placed around the distributing pipe, in practice, these sections 14 being joined at the end by connectors 15, also of cast iron, andwhich have an intermediate apertured annular flange 16, the opening in which is of a diameter corresponding to the diameter of the distributing axle, and being recessed at the ends to correspond to the diameter of the sections.

'l In Fig; 3w the sheathing is formed ofi-Cast I viron malesections 1 7 and female sections 18.
